AP2151A 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2151A is an integrated high-side power switches optimized for (Top View) Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and is available with active GND 1 8 NC high Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise time and under-voltage IN 2 7 OUT lockout functionality. A 7ms deglitch capability on the open-drain Flag IN 3 6 OUT output prevents false over-current reporting and does not require any external components. EN 4 5 FLG AP2151A is available in SO-8, MSOP-8EP, SOT25 and U-DFN2018- SO-8 6 packages.
